So far I have only hooked my HD laptop to my TV.  Im thinking about dedicated PC.  Ideas appreciated!

My hp Phoenix Envy computer plays my Phantom 3 Pro', 4K videos just fine.
But my monitor isn't 4K, so even though my videos look amazing, I still need to upgrade my monitor.

I simply pull the sd card from the drone and using the sd card adapter, download them to the desktop.
My tower has several slots for memory cards.


Useful for my Nikon D800 sd cards as well.

To play 4K video on 4K TV, you can take good advantage of some 4K media streaming devices such as Roku 4/Roku Premiere/Roku Premiere+, Chromecast Ultra, Amazon Fire TV, which all has perfect support for 4K video streaming from your local computer to 4K TV.
